摘要：VANETs are recent mobile wireless ad hoc networks which plays an important role in communications and various commercial applications. Routing of data is a challenge because of moving of the nodes ie., vehicles. Then the disconnection in between the nodes are always not predictable. The node which we are sending may be at our communication range at that moment, but after the sending of packet, due to some circumstances it may not reach the correct target. In the mean time the target node may go out of the transmission range. This happens due to many reasons like low packet delivery, increased packet overhead or routing overhead. In this paper we propose SCBGR(Step Clustering Based Greedy Routing) which is a position based routing algorithm which uses weight score method for efficient packet forwarding. We had used ns2.33 simulator. The routing overhead has been reduced considerably comparing to the recent routing protocols. The simulation results shows that SCBGR has overcome the limitations of the previous protocols.
